Detailed Description
In the present embodiment, the structure of a power battery system for an automobile is shown in fig. 1. Referring to fig. 1, a power battery system for an automobile includes a power battery module, a controllable connection module, and a control module.
The structure of the power cell module is shown in fig. 2. Referring to fig. 2, the power battery module includes a plurality of battery cells. In fig. 2, the battery cell may be the smallest unit of the power battery module, for example, one battery cell is one cell, or the battery cell may not be the smallest unit of the power battery module, for example, one battery cell is a battery module composed of a plurality of cells.
Referring to fig. 2, the battery cells are connected to form a first output circuit. Specifically, the battery cells may be connected in series, parallel, or a combination of series and parallel to form a first output circuit. Wherein the output voltage can be increased by series connection and the output current can be increased by parallel connection. In this embodiment, each of the battery cells may be arranged in a matrix as shown in fig. 2, where each of the battery cells belongs to a certain row and a certain column, and each of the battery cells in the same row may be sequentially connected in series, for example, in each of the battery cells in the same row, the positive electrode of the first battery cell is used as the positive electrode of the row, the negative electrode of the first battery cell is connected with the positive electrode of the second battery cell, and the negative electrode of the second battery cell is connected with the positive electrode of the third battery cell.
In this embodiment, on the basis of the first output circuit, a controllable connection module and a control module are further provided. One form of controllable connection module is shown in fig. 3.
Referring to fig. 3, a certain row of battery cells in a matrix-type power battery module is taken as an example, wherein a plurality of battery cells including a battery cell a, a battery cell B, a battery cell C, a battery cell D, a battery cell E, a battery cell F, a battery cell G, a battery cell H, etc. are connected, and a first output circuit is connected between the battery cells. The controllable connection module comprises a plurality of controllable switches, such as a controllable switch 000, a controllable switch 001, a controllable switch 002, a controllable switch 003, a controllable switch 004, a controllable switch 005, a controllable switch 006, a controllable switch 007 and the like, wherein one end of the controllable switch 000 is connected with the outside, the other end is connected with a first pole (a negative pole in fig. 3 or alternatively a positive pole in other embodiments) of a battery cell A, one end of the controllable switch 001 is connected with the negative pole of the battery cell A, the other end is connected with the negative pole of the battery cell B, one end of the controllable switch 002 is connected with the negative pole of the battery cell B, and the other end is connected with the negative pole of the battery cell C.
In this embodiment, a device such as a relay, a triode, a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor, a Metal-Oxide semiconductor field effect transistor), or an IGBT (Insulate-Gate Bipolar Transistor, an insulated gate bipolar transistor) may be used as the controllable switch. The control end of each controllable switch is connected with a control module, and the control module can independently control the on-off state of each controllable switch by sending a control level to each controllable switch.
For example, referring to fig. 4, the control module sends on-levels (which may be high) to controllable switches 000, 002, 003, 004, 006 and 007, which cause them to be on, and sends off-levels (which may be low) to controllable switches 001 and 005, which cause them to be off. Thus, the second output circuit in fig. 4 forms a conduction path through only the cell B (the cell to which the open controllable switch 001 is connected in the current direction) and the cell F (the cell to which the open controllable switch 005 is connected in the current direction).
According to the principle shown in fig. 4, for a power battery module in a matrix form, the on-off state of each controllable switch connected with a battery cell on the same column can be controlled, so that a conduction path in a column direction is formed, and the battery cell through which the conduction path specifically passes or does not pass can be controlled through the combination of the on-off states of each controllable switch; based on the same principle, the on-off state of each controllable switch connected with the battery cells in any same row can be controlled to form a conducting path in the row direction, and because one battery cell is positioned on a certain column and a certain row at the same time, the conducting path in the column direction can be controlled to pass through the battery cell, and meanwhile, the conducting path in the row direction is controlled to pass through the battery cell, so that the conducting path is turned at the position of the battery cell. Because the conduction path can be turned at any single battery cell, the control module can form the conduction path in any extending direction by controlling the on-off state of each controllable switch.
According to the principle, the control module can determine some specific battery cells as target cells in all the battery cells in a specific working state (first working state), and control the on-off of the controllable connection module according to the positions of the target cells, so that a conduction path passing through all the target cells but not passing through any non-target cells (the battery cells not belonging to the target cells) is formed in the first output circuit, and the energy provided by discharging all the target cells is output through the conduction path, namely the conduction path is the discharge path of all the target cells. And all non-target monomers, whether discharged or not, will not have energy flow through this conduction path.
In this embodiment, referring to fig. 1, the first power supply module is a low-voltage DC-DC module, the input end of the first power supply module is connected to the first output circuit, the output end of the first power supply module is connected to the VCU (Vehicle Control Unit, whole vehicle controller), the BMS, the monitoring and other uninterruptible electrical appliances, the second power supply module is a high-voltage DC-DC module, the input end of the second power supply module is connected to the second output circuit, and the output end of the second power supply module is connected to the high-voltage, high-power electrical appliances such as a motor, an air conditioner, and lamplight, but does not need to be uninterruptible.
In this embodiment, it is assumed that the first operating state is a complete vehicle power-OFF state (commonly called an IG-OFF state, in which no power is supplied to the uninterruptible electrical apparatus except for normal fire), the second operating state is a complete vehicle start-up state (commonly called an IG-ON state, in which power is supplied to the electrical apparatus of the complete vehicle),
In this embodiment, when the automobile is in the first working state (the power-off state of the whole automobile), referring to fig. 5, the control module controls the first power supply module to disconnect from the first output circuit, controls the second power supply module to connect to the second output circuit, and controls the on-off of each controllable switch in the controllable connection module, so as to form a conducting path (discharging path) only passing through the target monomer, controls each target monomer to discharge, and controls the battery monomer (non-target monomer) not belonging to the target monomer to stop discharging.
In this embodiment, when the vehicle is in the second working state (the starting state of the whole vehicle), referring to fig. 6, the control module sets all the controllable switches to the off state, so that no discharge path exists in the second output circuit, and each battery unit is not discharged through the second output circuit.
In this embodiment, when the control module performs the step of determining at least one target monomer, the control module may specifically perform the following steps:
S101A, detecting respective working parameters of each battery monomer;
S102A, setting a first threshold value;
S103A, screening out battery monomers with corresponding working parameters higher or lower than a first threshold value as target monomers;
S104A, planning a path according to the positions of the target monomers to obtain a discharge path.
Steps S101A-S104A are a first way of determining the target monomer.
In step S101A, the control module may invoke the battery management system to detect respective operating parameters of each battery cell. Specifically, the operating parameter to be detected may be one or more of voltage, temperature, discharge duration, and the like.
In step S102A, the control module sets a first threshold, where the first threshold is used to compare the magnitude of the operating parameter of each battery cell, and one first threshold may be set for each type of operating parameter. For example, a first threshold value of 3.5V may be set for an operating parameter of the type voltage, 40 ℃ may be set for an operating parameter of the type temperature, and 40min/h may be set for an operating parameter of the type discharge duration.
In step S103A, the target monomer may be screened out according to the magnitude relation between one or more working parameters and the first threshold value thereof. For example, if an operating parameter of the type having a voltage higher than a first threshold (3.5V) is selected, a battery cell having a temperature lower than the first threshold (40 ℃) may be selected as the target cell, if an operating parameter of the type having a temperature lower than the first threshold (40 ℃) is selected, and a battery cell having a discharge duration lower than the first threshold (40 min/h) may be selected as the target cell.
In step S104A, as shown in fig. 7, a shortest path is planned according to the positions of the target monomers, and the shortest path is obtained as a discharge path. Referring to fig. 7, the discharge paths obtained by performing steps S101A to S104A pass through each target cell (the electric power generated by the discharge of each target cell can be outputted through the discharge path) without passing through each non-target cell (the discharge path in fig. 7 passes through only the controllable switch turned on at the non-target cell position and does not flow through the non-target cell), and the length of the discharge path is the shortest among the paths all satisfying the requirements.
In the embodiment, the principle of executing the steps S101A-S104A is that firstly, target monomers meeting the requirements are screened out through working parameters and a first threshold value, the target monomers can be screened out according to the standards of highest voltage, lowest temperature, shortest discharge duration and the like, so that load and service life balance among different battery monomers can be realized, and a discharge path with the shortest length can be obtained by using path planning, thereby being beneficial to reducing the discharge loss of the target monomers.
In this embodiment, when the control module performs the step of determining at least one target monomer, the control module may specifically perform the following steps:
S101B, detecting respective working parameters of each battery monomer;
S102B, setting optimal parameters;
S103B, acquiring respective parameter deviation values of each battery monomer;
S104B, setting respective distance weights of the battery monomers according to the deviation values of the parameters;
S105B, planning a shortest path according to the positions of the battery monomers and the distance weights to obtain a discharge path;
and S106B, determining each battery cell passing through the discharge path as a target cell.
Steps S101B-S106B are a second way of determining the target monomer.
In step S101B, for each battery cell, one or more operating parameters such as voltage, temperature, discharge duration, etc. may be detected. For example, in this embodiment, the voltage, temperature, and discharge duration of each battery cell may be detected simultaneously, so that the operating parameters in the form of such vectors (voltage, temperature, discharge duration) are obtained.
In step S102B, the control module may invoke the battery management system to set an optimal parameter according to the current battery life, the history of use, the usage of the vehicle, and the like. The optimum parameters may be expressed in the form of vectors (optimum voltage, optimum temperature, optimum discharge duration).
In step S103B, for each battery cell, a module of a difference between the corresponding operating parameter (voltage, temperature, discharge duration) and the optimal parameter (optimal voltage, optimal temperature, optimal discharge duration) can be calculated as the parameter deviation value of the battery cell. The parameter deviation value indicates the degree to which the operating parameter of one battery cell deviates from the optimal state.
In step S104B, for each battery cell, a distance weight is set in positive correlation according to its parameter deviation value. In this embodiment, the distance weight is positively correlated with the parameter deviation value, and the parameter deviation value of one cell (or the processing such as dimensionality removal) may be used as the distance weight of the cell.
In step S105B, a shortest path is planned according to the positions of the battery cells and the distance weights, so as to obtain a discharge path. Specifically, referring to fig. 8, two battery cells (generally located at the edge of the power battery module) may be selected as a start point and an end point, respectively, and a shortest path planning algorithm is performed to perform a shortest path planning.
In step S105B, since each cell has a corresponding distance weight, when the shortest path planning algorithm is executed and the distance between the two cells is used, the respective distance weights of the two cells are considered. For example, in fig. 8, assuming that the distance weight corresponding to the battery cell a is the distance weight A and the distance weight corresponding to the battery cell B is the distance weight B, since the discharge path in this embodiment extends in the row and column directions of the matrix, the actual distance between the battery cell a and the battery cell B is d Actual practice is that of (a, B) =3, which means that the battery cell a is reached through 3 battery cells, and when the shortest path planning algorithm is performed, the distance between the battery cell a and the battery cell B input into the shortest path planning algorithm may be the weighted distance d Weighting of (a, B), specifically, the weighted distance d Weighting of (a, B) may be calculated by the formula d Weighting of (A,B)＝d Actual practice is that of (a, B) ×the distance weight A ×the distance weight B.
In step S105B, the shortest path planning algorithm may obtain the shortest path by traversing all non-repeated paths between the start point and the end point to obtain the shortest path. In step S106B, each battery cell through which the shortest path passes (for example, each battery cell overlapping with the shortest path in fig. 8) is determined as a target cell, and the shortest path is determined as a discharge path, and the control module refers to the principle of fig. 4, and sets the controllable switch through which the discharge path passes to be in an on state, and sets the controllable switch not through which the discharge path passes to be in an off state, so that each target cell can discharge and output electric energy through the discharge path, while the non-target cell does not discharge through the discharge path.
In this embodiment, the principle of executing steps S101B-S106B is that after the actual distance is weighted by using the distance weight determined by the parameter deviation value, a discharging path is planned by using the shortest path planning algorithm, and a discharging path can be determined first, and the discharging path considers the influence of the actual distance between the battery cells, and also considers the working parameters of each battery cell, so that a discharging path with better comprehensive aspects of discharging loss, working parameters and the like can be obtained, and after the discharging path is determined, the target cell is determined, and under the condition that the working parameter difference between each battery cell is not obvious, the discharging loss and the whole working parameter performance can be optimized.
In this embodiment, the control module may further perform uninterrupted health detection on each battery cell. For example, the control module may invoke the battery management system to monitor each battery cell in real time in the first working state, so as to obtain the respective health degree of each battery cell. The control module marks the battery monomer with unqualified health degree, and when the steps of S101A-S104A or S101B-S106B and the like are executed to determine the target monomer, the marked battery monomer is not determined to be the target monomer, so that damage to the unhealthy battery monomer is reduced, and stable power supply in the first working state is ensured.
The "first output circuit" and the "second output circuit" and the like mentioned in the present embodiment are referred to as "output circuits" in the context of the power battery module being in a discharge state in the embodiment, which circuits are used to output electric energy generated by discharging each battery cell, and in fact these output circuits may also receive external electric energy to charge each battery cell when the power battery module is in a charge state, so these output circuits are also "input circuits" in practice. Similarly, the "first power supply module" and the "second power supply module" in this embodiment may also receive external electric energy to charge each battery cell when the power battery module is in a charged state, so these power supply modules are also "charging modules" in practice.
